| Abstract: | The porthole die extrusion can often be used to produce the section extrusion of nonferrous met- als. Based on the results of numerical simulation and the experimental results of practical extrusion pressure for MB2 alloy, this paper gives a simple engineering algorithm of the extrusion force during the process of the porthole die extrusion. Compared with the experimental results, the algorithm has less than 10% relative error. Therefore, it can be reference for the practical application. |
